Reaction Name: Electrophilic Addition
Reaction Mechanism: Markovnikov’s Rule (Carbocation Intermediate)
Equation:

CH2=CH2+HBr→CH3CH2Br (major product)\text{CH}_2\text{=CH}_2 + \text{HBr} \rightarrow \text{CH}_3\text{CH}_2\text{Br} \, (\text{major product})CH2​=CH2​+HBr→CH3​CH2​Br(major product)

Major Product: 1-Bromethane (CH₃CH₂Br)
Minor Product: 2-Bromethane (CH₂BrCH₃)
Mechanism: The mechanism involves the formation of a carbocation intermediate, and the proton (H⁺) adds to the carbon with the greatest number of hydrogen atoms (Markovnikov's rule), leading to the major product.g
